Question : I'M driving a
2006 Toyota Estima.
When I'm driving in the rain and the speedometer exceeds 110km/h, the
steering wheel starts to vibrate and as the speed picks up, the vibrations
As long as I maintain the speed below 110km/h, no vibration is felt.
When driving in dry condition, everything is normal.
After purchasing the MPV sometime
in January 2008, the tyre was changed
to 225x50x17 size together with a two-piece rim.
I have consulted a few mechanics
and tyre repair technicians and they
inform me that it Is either due to the
two-piece rim that I'm currently using
or something is wrong with my ABS
I have carried out a diagnostic check
on the car and was informed that everything is OK. I doubt that it has any-
thing to do with the two-piece rim.
My MPV specifications are: Model
- DBA-ACR50W-GRXEK; Engine - 2A2-
FE; Frame # - ACR50-7002502.
Some cars can be quite sensitive to
particular imbalances and one needs to
go about it systematically to find the
cause and rectify it.
I suspect that the problem is a combination of the two-piece rim and the
Firstly, you need to confirm if the rims have the same offset as the
original wheels and secondly, if there is any defect in either of the front tyres.
The easiest test is to put back the original wheels and tyres (or borrow a set),
and if there is no vibration or wobbling,
you can be sure that it is related to the
new wheels and tyres.
If there is no vibration after testing
with the original wheels, swap the new
front and rear pairs, i.e. front to rear and
vice versa and see if the problem goes
If it does, then you have isolated the
problem to only two wheels and tyres.
You then need to check them carefully
for run-out, tread inconsistency, etc.
